Table 8-3: Optimization parameters in FFT mode
Optimization mode
Description
DYNamic
Optimizes the dynamic range by using the narrowest possible partial span (depend-
ing on the RBW).
The autorange function for the internal IF gain calculation is activated to obtain the
best control range for the A/D converter.
SPEed
Optimizes the sweep rate by using the widest possible partial span (depending on
the RBW).
The autorange function for the internal IF gain calculation is deactivated. (Note: set
the reference level accordingly to optimize the control range for the A/D converter).
It is recommended that you set the
to "Auto" to optimize the sweep
rate.
AUTO
Uses a medium-sized partial span to obtain a compromise between a large dynamic
range and a fast sweep rate.
The autorange function for the internal IF gain calculation is activated to obtain the
best control range for the A/D converter.
Zero span mode
For zero span measurements, the optimization mode defines the selection of the A/D
converter prefilter.

Optimization mode
Description
DYNamic
The narrowest filter possible (depending on the RBW) is used.
SPEed
The widest filter possible (depending on the RBW) is used.
AUTO
A medium-sized prefilter is used.
Parameters:
<Mode>
*RST:
AUTO
Example:
SWE:OPT DYN
Selects optimization for dynamic range.

<SweepPoints>
This command defines the number of sweep points to analyze after a sweep.
Note that the number of sweep points is limited to 10001 when measuring spurious
emissions.
Parameters:
<SweepPoints>
Range:
101 to 100001
*RST:
1001
Example:
SWE:POIN 251
